Answer:
Meiosis is a process of gamete formation in which diploid germ-line cells, i.e., the cells that are set aside early in animal development for sexual reproduction, yield four genetically different haploid cells. It occurs only in sex cells, which are eggs and sperms.
Phases
Meiosis takes place in two stages - Meiosis I, where DNA replication takes place and crossing-over occurs; and Meiosis II, which lacks DNA replication, but is similar to Mitotic cell division.
